The through shelf is also called the corridor shelf and the driving shelf. It is a continuous shelf that is not separated by passages. On the supporting track (bracket beam), the tray is stored along the depth direction, and one immediately exists, which makes high density storage possible. The through shelf is suitable for storing small and large quantities of goods. It is usually used to store a large number of goods of the same type. It has high space utilization rate and is suitable for high storage space cost in food industry, chemical industry, clothing industry and refrigeration. Its unit storage cost is relatively low.

Through shelves can be divided into one-way and two-way layout according to the direction of extraction. The total depth of one-way (wall area) shelf is better controlled within 6 pallet depths, and the total depth of two-way (middle area can be picked up on both sides) shelf area. In order to improve the efficiency and reliability of forklift passage, the depth of 12 pallets should be better controlled. (In this type of shelf system, the forklift is a continuous "high lift" operation, the forklift is easy to sway and crash into the shelf, so the stability is very important to consider whether it is sufficient.)

This kind of storage system is not stable and the shelf should not be too high. Usually it should be controlled within 10 meters in order to enhance the stability of the whole shelf system. In addition, in order to have larger specifications and choices, a hoisting device must be added. Single pallet cargo should not be too large or too heavy. Usually the weight should be controlled within 1500 KG, and the pallet span should not be greater than 1.5 meters. Forklift trucks are usually forward battery forklift trucks or counterweight battery forklift trucks.
